The passage behind the door looked just pitch black from the water, as if nothing was left.

But when Ge Dongxu tried to enter, he suddenly realized that the dark passage seemed to have a heavy thing. He needed to use his strength to step in. As soon as he stepped in, he felt a force squeezed from all directions.

The power made Ge Dongxu subconsciously activate his true energy, and then he felt a little relaxed all over.

However, Ge Dongxu felt relieved. Xu Lei, Lu Xinghai and Zhu Dongyu, who followed him in, were suddenly pressed by the force that suddenly came from all directions in the passage and knelt on one knee on the ground, making him breathing a little difficult.

Without Ge Dongxu's explanation, the three of them immediately activate their true energy so that they can slowly stand up.

However, they were not as relaxed as Ge Dongxu. Every step they took was like carrying a thousand pounds. After a few steps, cold sweat broke out on their foreheads, and their legs seemed to be filled with lead.

The three of them all looked shocked, and then they understood why the secret realm was opened, and at least the fourth level of Qi training was required to be qualified to enter. It is estimated that entering this passage below the fourth level of Qi training was impossible to even walk.

"The barrier is the legendary barrier prohibition!" Just as the three of them looked shocked, Ge Dongxu was curious and wondering what this passage was, and the voice of Yuan Xuan Zhenren sounded behind him.

The disciples of Shushan Sect came in immediately behind Xu Lei and the others.

"The barrier ban?" Ge Dongxu was slightly stunned.

Although he had Ge Hong's complete inheritance in his mind, many profound inheritances, with his current cultivation level, could only vaguely know that they were hidden in his sea of ​​consciousness, but they could not unblock them. Just like the Five Elements Universe Stone, Ge Dongxu could not even sense it in any place in the sea of ​​consciousness.

Obviously, the barrier restriction is far from the profound magic that Ge Dongxu can use now, so even if he has a large amount of cultivation, he doesn't know it.

"Yes, barrier ban. This is a magic trick that only warlocks with great magic power can be used in ancient times. This magic trick is said to be able to isolate a place from the real world space, so that outsiders can not only not see it, but they can't even enter it." Yuan Xuan Zhenren explained.

"How is this possible?" Xu Lei and the other two exclaimed in disbelief.

"We can't understand the mystery of ancient magic!" Yuan Xuan Zhenren sighed, and his eyes showed a look of yearning.

"The reason why we feel incredible and infinite mystery is that we do not have the ability to build this barrier. If we really have the ability to build one day, we will think that this is just a very ordinary thing." Ge Dongxu said thoughtfully after hearing this.

"True Ge really loves to joke. If we really have the opportunity to reach the height of the ancients, this barrier ban is naturally nothing." The two elders of Laoshan who arrived later said.

Ge Dongxu smiled faintly, without explanation, but Xu Lei and others who knew him, Yuan Xuan Zhenren and Xu Kong Zhenren all looked thoughtful.

However, Xu Lei and others soon had no intention of thinking about such profound questions, because the power oppressed from all directions required them to use their full strength to move forward slowly, and they had no spare time to think about other things.

However, Zhenren Yuan Xuan had a high level of cultivation, although he could not be as "easy" as Ge Dongxu, but he was also at ease. He walked side by side with Ge Dongxu, thinking about what Ge Dongxu said before, but he got nothing.

"What explanation did Zhenren Ge just say? Please give me some advice." After walking for a while, Zhenren Yuan Xuan couldn't help but whisper.

"Actually, it's nothing. I just had a sudden idea." Ge Dongxu replied modestly when he heard this, and then continued: "In fact, if a real person regards the barrier prohibition as the wall of the house we built, or the outer wall of the container we built in reality, then the space and things inside the barrier restriction are the space and things in our house."

"How can this be compared?" Yuan Xuan Zhenren blurted out subconsciously when he heard this.

"What can't be compared? The walls of a house or the outer wall of a container play a role in isolating the same space, just like this barrier restriction. It's nothing more than the outer walls of a container that we know and can see, but the barrier restriction is another invisible energy substance that requires magic to be constructed. Our cultivation is still low now and cannot reach the height of using magic to build barrier restriction, so this barrier restriction seems very incredible and mysterious to us. Just like when the glass container first appeared, people who have never seen it must also feel very magical. Why is it clearly transparent, but you can see the things inside but don't leak." Ge Dongxu replied naturally.

After hearing Ge Dongxu's words, Yuan Xuan was stunned and looked at Ge Dongxu with his eyes as if he was looking at a monster.

He used to think of such a profound technique, but after Ge Dongxu explained it, it turned out to be such an ordinary thing. He could not imagine what the brain of the young man in front of him was, and why he could associate such a profound technique with such an ordinary secular thing. Zhenren Piansheng Yuanxuan felt that he was very inspired and thought that he was very reasonable.

How could Master Yuanxuan know that they put the practice of Taoism at the beginning and were in awe of it psychologically. It can be said that they were completely at a disadvantage in their mentality, so many Taoisms naturally thought about it in a profound and complex manner, and even felt like walking on thin ice. Ge Dongxu was just the opposite. From the beginning, he regarded practice as a science, and from the psychological point of view, he was completely relaxed. Therefore, many magical techniques that seemed very profound to Master Yuanxuan, and Ge Dongxu often pointed directly to its essence.

In fact, the reason why Ge Dongxu made such rapid progress in this Dharma-Ending Age is closely related to his mentality, and it is not just an opportunity.

"Does the real person think my idea is strange? Comparing these barrier bans to houses and glass containers is too simple? In fact, it is not the case. If you think deeply, in the earliest era, when people could not even build houses, let alone the high-rise buildings nowadays, even ordinary brick and tile houses are very profound things. But when science develops step by step, those high-rise buildings that are hundreds of meters high are beginning to become unsurprising. I think barrier bans should actually be the same. The way is simple, and many things seem very profound and unpredictable on the surface. When one day we truly understand the secrets, we will find that they are actually very simple." Ge Dongxu saw Yuan Xuan staring at him, thinking about it and then said.
